Who Invented Roller Skates?

No one really knows who invented roller skates or even when they first used.  They were probably invented by ice skaters in Europe, some 200 years ago, who wanted to skate when there was no ice.

Roller skating is the popular sports of skating on wheeled skates.  People were roller skating on the roads of Holland and Belgium  about 200 years ago. 

Some early skates had several wheels in a line like the blade of an ice skate.  Others had only two wheels.

In 1862, a man named John L. Plympton of Boston invented the four-wheel skate, much like those we skate on today.  These skates made roller skating widely popular.

The first skates had wooden wheels which broke easily.  The next development was the introduction of all-metal skates with ball bearings in the wheels to make them turn faster.  This completed the skate as we know it today.

Skating to music at indoor rinks is a year-round sport followed by many thousands of skating enthusiasts.–Dick Rogers

Surfing


Surfing is a sport originated in Hawaii in which a person standing on a long narrow board is borne by breakers toward the shore. The sport is now enjoyed on the open ocean coastlines throughout the world. Best conditions occurs where large, smooth ocean swells in deep water peak up into steep-sided sets of waves, or breakers, as they encounter a shelflike reef or sandbar 100 to 1,000 yards (90 to 900 meters) from shore. The lee side of a point of land or a jetty often has the proper bottom line for good surfing waves. Under ideal conditions, riders surf half a mile or more.

Where surf is light, flat boards 4 to 6 feet long by a foot wide are used. For waves up to 20 feet in height, a tapered, hollow surfboard 10 to 12 feet and 2 feet wide, with a stabilizing fin, or skeg, near the back, is necessary. The rider first swims out beyond where the larger rollers peak up. As a wave approaches him, he paddles his board toward shore to attain sufficient speed to coast down the face of the wave. Once he has caught the wave, he may rise to a standing position and ride it until it dies out near the beach. To increase speed and distance, experts ride diagonally toward shore.

The wakes of heavy outboard and inboard motorboats driven at speed of 9 to 13 miles per hour provide waves of sufficient strength for less difficult “surfing” on inland lakes and rivers. The rider starts with towline from the boat and lets it go when he feels the wake pushing him. Wave-making machines were also developed to allow lake and river surfing.
